How to Fully Recover Data from a Brick Android Device

"I believe I have accidentally 'bricked' my device (Huawei G330, model U8225-1). While performing an ADB push, I received an error message stating 'push failed: no space left on device.' Now, the phone boots into recovery mode, and it is rooted, but the bootloader is locked. When I attempt to push an update to the SDCARD/dload folder, it says 'no such file or directory.' If I try to access an ADB shell, it responds with 'exec '/system/bin/sh' failed: Permission denied (13).' How do people typically handle a dead or bricked smartphone? I'm hoping there's a way to recover data from a bricked Android, is that feasible?"

There are two categories of bricking: soft brick and hard brick. A soft brick occurs as a result of software issues, whereas a hard brick in an Android phone is typically caused by hardware malfunction. To elaborate, most Android devices become bricked or non-functional due to accidental drops or impacts, installation of a custom ROM that is incompatible with the device's hardware, disappearance of Google apps following the installation of a custom ROM, mismatch between the custom ROM and the installed kernel, or errors during the process of wiping full data, performing a factory reset, or clearing the cache after flashing a custom ROM.

How to Unbrick Your Android and Backup Data?

The term "bricked" implies that your Android phone is completely unresponsive and cannot be turned on in any manner, rendering it unusable. If your device is stuck in a boot loop or recovery mode, it's fortunate that it's not truly bricked. You still have the option to restore it to normal functionality by flashing a ROM.

One of the best things about the openness of the Android platform is that if you're unhappy with the stock OS, you can install one of many modified versions of Android (ROMs) on your device. A new ROM can bring you the latest version of Android, allowing you to overcome issues like an endless looping system and a frozen screen that make your Android device seem unusable.

So far, Android operating system under 8.0 version is open for the public to flashing a ROM. If you're not so good at those Android tricks and skills, send the device to a maintenance center, asking the specialists there to flash the ROM for you. Or, just google some tutorials and do it yourself at home.

When performing the Android flashing process, you have the option to retain your data. Therefore, exercise extreme caution when attempting to fix a bricked phone while flashing a ROM.

How to Recover Data from Android After Flashing ROM Flashing a new ROM on your Android device can be an exciting way to customize and optimize its performance. However, this process often results in the loss of existing data. If you've flashed a new ROM and now need to recover your data, follow these steps: 1. **Backup before Flashing (Precautionary Measure):** Before you flash any new ROM, it's crucial to create a backup of your important data. This can be done using apps like Titanium Backup (if you have root access) or by using Android's built-in backup feature to save data to Google Drive. 2. **Restore from Backup (If Available):** If you've made a backup prior to flashing, simply restore your data from the backup file. For rooted devices with Titanium Backup, open the app, and select "Restore." Choose the appropriate backup set and proceed with the restoration process. 3. **Use Data Recovery Tools:** In case you didn't create a backup or the backup is not available, there are several data recovery tools available for Android. Some popular options include Dr.Fone, tools MobiSaver, and DiskDigger. These tools scan your device's memory for deleted or lost files. - **Download and Install:** Download the chosen data recovery tool on your computer and install it. - **Connect Your Device:** Connect your Android phone to the computer using a USB cable. - **Enable USB Debugging:** Go to "Settings" > "Developer options" on your Android device, and enable USB debugging if it's not already turned on. Note that "Developer options" might be hidden; to access it, go to "About phone" and tap on "Build number" seven times. - **Launch the Software:** Run the data recovery software on your computer, and select the type of files you want to recover (e.g., contacts, messages, photos). - **Scan Your Device:** Initiate the scanning process. This may take some time depending on the size of your data and the tool being used. - **Preview and Recover:** Once the scan is complete, the software will display the recoverable files. Preview them and select the ones you want to recover. Click on "Recover" to save them to your computer or back to your Android device. 4. **Contact Cloud Services:** If you had synced your data with cloud services like Google, Facebook, or WhatsApp, you can log in to those accounts and retrieve your data from there. 5. **Seek Professional Help:** If all else fails, consider seeking assistance from professional data recovery services. They may be able to retrieve your data through more advanced methods, although this could be costly. Remember, prevention is always better than cure. In the future, make sure to create regular backups to avoid losing important data when flashing a new ROM.

When flashing a ROM, you're presented with two options: "Wipe Data/Factory Reset" or "Wipe Cache Partition." If you haven't backed up your data previously, flashed ROMs can result in varying degrees of data loss.

• "Wipe Data/Factory Reset" is selected when you're flashing a ROM different from the one you're currently using. This will result in the loss of all your data.
• "Wipe Cache Partition" is for installing a new version of a ROM that you're already running. This way, you can retain some of your data, apps, and settings.

Therefore, if you're merely wiping data and cache instead of performing a factory reset, you can utilize tools like MobiSaver for Android to recover data from your Android device after flashing a ROM. While it cannot assure a complete retrieval of all lost data, it's certainly worth attempting to regain as much as possible.
